OneDrive is the Microsoft cloud service that connects you to all your files. It lets you store and protect your files, share them with others, and get to them from anywhere on all your devices. When you use OneDrive with an account provided by your company or school, it's sometimes called OneDrive for Business.

If you’re using Office 365, you get at least 1 TB of space in the cloud, depending on your plan. If your OneDrive for Business library is hosted on a SharePoint server in your organization, your organization’s administrators determine how much storage space is available.

All files that you store in OneDrive for Business are private unless you decide to share them. You can share files and folders with co-workers so you can collaborate on projects. If you’re signed-in to Office 365, you may even be able to share with partners outside of your organization, depending on what your company allows.

Tip: When you send email from Outlook Web App, you can attach a OneDrive for Business file as a link, instead of sending an attachment. When you Attach a file as a link, you automatically give the people you send the message to permission to edit the file. Plus, you save space in everyone's mailbox and encourage people to edit the same copy in OneDrive for Business.

To sync OneDrive for Business with your local computer, you'll need the OneDrive for Business sync app which lets you Sync files to your PC or Mac. This sync app is available with Office 2013, Office 2016, or with Office 365 subscriptions that include Office 2016 applications. If you don’t have Office, a free download of the OneDrive sync app is also available.

It's all OneDrive, which means you use the same apps to sync files down to your Windows PC or Mac, or get to your files from your Android or iOS device. You just sign in with your work or school account to use OneDrive for Business, or sign in with your Microsoft account to use OneDrive personal.

Use OneDrive to save documents, photos, and other files in the cloud, share them with friends, and even collaborate on content. When you subscribe to Office 365, you get 1 TB of storage and premium OneDrive features.
